Vocabulary Review Ch 28 – Plant Evolution and Classification
A waxy or fatty and watertight layer on the external wall of epidermal cells Cuticle
A reproductive cell or multicellular structure that is resistant to environmental conditions and that can develop into an adult without fusion with another cell Spore
The specialized conducting tissue that is found in higher plants and that is made up mostly of xylem and phloem Vascular tissue
The type of tissue in vascular plants that provides support and conducts water and nutrients from the roots Xylem
In vascular plants, the tissue that carries organic and inorganic nutrients in any direction, depending on the plant’s needs Phloem
The three groups of plants (liverworts, hornworts, and mosses) that lack specialized conducting tissues and true roots, stems, and leaves Nonvascular plant
A plant that has true roots, stems, and leaves and a vascular system composed of xylem and phloem which are specialized tissues that conduct materials from one part of the plant to another Vascular plant
A plant that produces seeds Seed plant
A woody, vascular seed plant whose seeds are not enclosed by an ovary or fruit Gymnosperm
A flowering plant that produces seeds within a fruit Angiosperm
In plants and algae that have alternation of generations, the diploid individual or generation that produces haploid spores Sporophyte
In alternation of generations, the phase in which gametes are formed; a haploid individual that produces gametes Gametophyte
The alternation of sexual reproduction and asexual reproduction in certain plants and animals Alternation of generations
A plant that has no vascular tissue and absorbs nutrients and water from the soil through root-like hairs; examples include mosses and liverworts Bryophyte
A member of the phylum Hepatophyta, a unique group of bryophytes that grow close to the ground in moist, shady areas and that are characterized by unique structures on the gametophytes Liverwort

In the female reproductive system of animals, an organ that produces eggs; in flowering plants, the lower part of a pistil that produces eggs in ovules Ovary
The embryonic leaf of a seed Cotyledon
A monocotyledonous plant; a plant that produces seeds that have only one cotyledon Monocot
A dicotyledonous plant; an angiosperm that has two cotyledons, net venation, and flower parts in groups of four or five Dicot
In plants, a bundle of vascular tissue that transports fluids and nutrients; in animals, a vessel that carries blood to the heart Vein
A parallel arrangement of veins; typical of the leaves of monocots Parallel venation
A nonparallel, branching network of veins that is typical of the leaves of dicots Net venation
